Crater Lake in July: what the park service says

July begins what the park service calls Crater Lake's well-defined summer, which runs to mid-September. In recent years the East Rim Drive opened between June 11 and July 22, so the full loop may only just be open in early July. Plan around one change: the Cleetwood Cove Trail is closed for a major construction project until 2029.
